Popis:	Ni2B nanoparticle distributed on ordered SBA-15 mesoporous silica was prepared in situ and its catalytic activity for NaBH4 hydrolysis was investigated in the presented paper. The problem of Ni2B aggregation is resolved and the catalytic activity of Ni2B is also improved due to the effect of SBA-15. The catalytic activity increases with Ni2B/SBA-15 weight ratio increased from 1:4 to 2:1 and the catalyst with Ni2B/SBA-15 weight ratio of 2:1 has high catalytic activity close to that of Ni2B. The sintered experiment shows that the catalytic activity comes from amorphous Ni2B, not crystalline Ni2B. High sintering temperature leads to the conversion from amorphous Ni2B to crystalline Ni2B and damages the nanostructure of amorphous Ni2B framework.
